Examples Kubevirt

Create VM (kubevirt.io/v1alpha3, Debian 9):

                  root:toor
                expire: False
EOF

Conect to vm:

kubectl get vms
virtctl start debian

virtctl console debian

Create VM with Debian 10

Currently Debian 10 has problems to start with cloud-init, you can use the following example to use it and solve the problem temporarily.

cat <<EOF | kubectl apply -f -
apiVersion: kubevirt.io/v1alpha3
kind: VirtualMachine
metadata:
  name: debian
spec:
  running: false
  template:
    metadata:
      labels: 
        kubevirt.io/size: small
        kubevirt.io/domain: debian
    spec:
      domain:
        cpu:
          cores: 2
        devices:
          disks:
            - name: containervolume
              disk:
                bus: virtio
            - name: cloudinitvolume
              disk:
                bus: virtio
          interfaces:
          - name: default
            bridge: {}
        resources:
          requests:
            memory: 1024M
      networks:
      - name: default
        pod: {}
      volumes:
        - name: containervolume
          containerDisk:
            image: tedezed/debian-container-disk:10.0
        - name: cloudinitvolume
          cloudInitNoCloud:
            userData: |-
              #cloud-config
              bootcmd:
                - echo cloud-init=disabled > /etc/cloud/cloud-init.disabled
                - [ /bin/bash, -c, 'echo -e "demopass\ndemopass" | passwd root' ]
                - reboot
EOF

Example in docker

Example: docker pull tedezed/debian-container-disk:8.0

Customizable use

Edit the file build_variable with your OS images, personal Docker registry and execute the next command to compile:

source build_variable
make build

kubevirt-images-generator's Issues

Ubuntu jammy-jellyfish is the LTS for 2022, not Kinetic Kudu

I happened upon your images via this blog and saw that when i loaded 22.0 -- i was presented with Kinetic Kudu.

Could your build_variables point at a different server image?

Ubuntu vm

I have been playing with this, but I cant seem to figure out the username / password to login to the ubuntu vm

using qemu , I know its a non issue just did not know where else to post this

container-disk-v1alpha base image is not needed/recommended anymore.

And also cause of python3.7 the yum update its broken.

Now the recommended way is from scratch just add the image. and qcow2 is the recommended one.

https://kubevirt.io/user-guide/docs/latest/creating-virtual-machines/disks-and-volumes.html#containerdisk-workflow-example

so something like this should be better:

FROM alpine as BUILDER
ARG IMG_URL="https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img"

RUN wget $IMG_URL -O ubuntu.qcow2
# ubuntu publish the qcow2 images as .img -.-
FROM scratch
copy  --from=BUILDER /ubuntu.qcow2 /disk/

I am creating the images in this repo: https://github.com/zakkg3/kubevirt-images

but it still needs some automation as you did for this one.

Cheers!

Is that possible to create images of Windows?

As I mentioned in the title. Or please leave a comment if there is anyone have an idea about this. Thanks for that.
